This disclosure provides systems, methods, and devices for wireless communication that support techniques for optimizing amplification parameters of repeaters based on signal characteristics. In aspects, a repeater determines at least one of power of a first signal received from a first wireless communication device or power of a second signal received from a second wireless communication device, adjusts at least one of a first amplification parameter associated with the first signal or a second amplification parameter associated with the second signal based, at least in part, on at least one of the determined power of the first signal or the determined power of the second signal, and transmits at least one of the first signal based, at least in part, on the adjusted first amplification parameter or the second signal based, at least in part, on the adjusted second amplification parameter.

Technology for a repeater is disclosed. The repeater can include a first antenna port and a second antenna port. The repeater can include a first uplink analog signal amplification and filtering path and a second uplink analog signal amplification and filtering path. The repeater can include a first downlink analog signal amplification and filtering path and a second downlink analog signal amplification and filtering path. The repeater can include an uplink software-defined filtering (SDF) module and a downlink SDF module.

A technology is described for a time division duplex (TDD) repeater with network protection. The TDD repeater can comprise a first port, a second port, and one or more amplification paths coupled between the first port and the second port. The TDD repeater can comprise a signal detector configured to measure a received signal power for a downlink (DL) signal in a first set of one or more TDD DL subframes. The TDD repeater can be further configured to adjust an uplink (UL) noise power or gain of the one or more amplification paths based on the received signal power for the DL signal in the first set of the one or more TDD DL subframes.

Methods, systems, and devices for wireless communication are described. A wireless repeater beamforms a receive signal, at a first antenna array. The repeater retransmits, via a second antenna array, a beamformed signal. The repeater may adjust the receive and/or transmit beam in order to avoid signal interference caused by the retransmission. The repeater may monitor an output of a power amplifier (PA) in a signal processing chain and adjust a gain to a PA driver to the PA and/or a gain to one or more low noise amplifiers (LNAs) in the signal processing chain in order to improve or maintain transmission stability in the repeater.

A relay amplification method and system, and a storage medium are provided in the present disclosure. The relay amplification system includes a first antenna, a first RF transceiver, a second RF transceiver, and a second antenna which are connected in sequence, and the relay amplification method includes: determining whether power of a first I/Q signal output by the first RF transceiver changes with respect to power of a second I/Q signal output by the first RF transceiver; and if yes, controlling a gain of power adjustment for the first RF transceiver and a gain of power adjustment for the second RF transceiver respectively according to a power variation of the first I/Q signal, to make the power of the first I/Q signal remain unchanged with respect to the power of the second I/Q signal and a link gain between the first antenna and the second antenna remain unchanged.

An active scattering device comprises a set of N identical single chain RF devices functioning as repeaters or transponders, which are placed adjacent to each other and in parallel over an area of active scattering, where N is an integer ≥2. Each of the N identical RF devices includes a receiving aperture, having a first coverage, for receiving a first signal within the first coverage; and a transmitting aperture, having a second coverage, for re-radiating a second signal within the second coverage, the second signal being received by one of the respective receiving apertures of the N identical RF devices. In various embodiments, the active scattering device is configured to function as a reflective directional repeater/transponder, or a retro-directive repeater/transponder, or a 2-D directional repeater/transponder that is retro-directive in a first dimension and reflective in a second dimension perpendicular to the first dimension.

Embodiments describe systems, apparatuses, and methods for transmitting/receiving signal data to/from a plurality of transceiver modules. Devices in accordance with some embodiments can include a plurality of wireless transceiver modules, each wireless transceiver module to be communicatively coupled to a corresponding external transceiver module, one or more antennas to exchange signal data with the plurality of external transceiver modules, a radio frequency (RF) circulator, and one or more amplifiers to amplify the signal data received by the one or more antennas and signal data to be transmitted by the one or more antennas. The use of circulator prevents transmitting signals that may collide with each other and cause interference with the communications.

An integrated repeater system that includes a repeater device having a first surface and a second surface that is opposite to the first surface. The repeater device further comprises phased array antenna receivers arranged on the first surface and receives a mmWave radio frequency signal from a base station, and one or more phased array antenna transmitters arranged on the second surface and transmits the received mmWave radio frequency signal through a glass structure to a user equipment. The integrated repeater system further comprises an impedance matching component between the second surface and the glass structure. Further, an impedance of the one or more phased array antenna transmitters is tuned in accordance with the glass structure based on the impedance matching component.

A repeater system includes a first repeater device to receive a first beam of radio frequency (RF) signal from a first network node, and a second repeater device to receive a second beam of RF signal from the first network node. The first repeater device controls the second repeater device to provide the first beam and the second beam of RF signal to a second network node. A plurality of signal parameters is selected at the first and second repeater devices for a first beam and a second beam of RF signal, respectively. The first repeater device establishes an additional link with the second repeater device, where based on the additional link, a first data stream carried by the first beam of RF signal is provided to the second network node through the first repeater device as well as the second repeater device.

This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. For example, a communication system may include a repeater having a first communication interface that receives a control message that indicates a measurement configuration for a second communication interface of the repeater that is different than the first communication interface. The repeater receives, via the second communication interface, a first signal at the repeater from a first device. The repeater also measures a power metric associated with the first signal based on the measurement configuration. In some implementations, a base station or another device (e.g., UE), may communicate with the repeater and take one or more actions based on the power metric measured by the repeater.
